Milling cutter replacement device

Abstract

The invention discloses a milling cutter replacement device. A first through hole is arranged along a circumferential direction on a milling cutter shaft (1). A second through hole corresponding to the first through hole is arranged on a milling cutter seat (2) used for fixing a milling cutter. A steel ball (12) is arranged in the first through hole. A compression rod (8) capable of moving up and down is arranged in the milling cutter shaft (1). When the compression rod (8) moves up to a first position, the steel ball (12) is stuck in the first through hole and the second through hole, such that the milling cutter seat (2) is fixed with the milling cutter shaft (1). When the compression rod (8) moves down to a second position, the steel ball (12) departs from the second through hole, such that the milling cutter seat (2) can slip off from the milling cutter shaft (1), and milling cuter rapid replacement is realized. The device has a simple structure. With the device, remote replacement can be carried out by a manipulator in a hot chamber, such that the chances for stuffs to enter the hot chamber are minimized. Therefore, radiation hazard is reduced, and working efficiency is improved.

Description

technical field [0001] The invention relates to a component dismantling machine, in particular to a milling cutter replacement device, which is used for remotely replacing the milling cutter on the component dismantling machine with a manipulator in a hot chamber. Background technique [0002] A hot cell is a shielded, sealed containment device equipped with an operating system. It is often used for high-radioactivity experiments and operations, and protects operators from exposure to radiation greater than the allowable dose during operations. Various heat chamber machines with compact structure and complex functions are installed in the heat chamber, and are operated by manipulators. Among them, the component dismantling machine is one of the commonly used hot cell machines, and the milling cutter is an important part of the component dismantling machine, which is used to cut components, so it needs to be replaced frequently. [0003] At present, the replacement of the mi...

Problems solved by technology

Due to the special environment in the hot chamber, there are various radioactive particles such as α and β. In order to ensure the safety of the operator, the operator needs to wear protective clothing when entering the hot chamber to replace the milling cutter, which increases the probability of the operator being exposed to radiation hazards. Second, when entering and leaving the heat chamber, operations such as transferring components and cleaning the heat chamber are required to reduce the radiation dose. There are many steps, which seriously affect the work efficiency
